This is why I loved studying exercise science in college. I could listen to people talk about stuff like this all day. It’s unlikely that most rowers will ever think about the actual process of muscle memory on a cellular level like this but once you break it down, you realize how much of a process learning the stroke really is. I think that if you understand the science behind it, in a way it makes things less frustrating because you know that all these things have to happen in order for you to gain proficiency with your stroke and those things can’t/don’t just happen overnight.
One of the biggest things that I think everyone should take away from this is how important it is for you to consciously be thinking about the changes you’re making or trying to make. (That applies to coxswains too, not just rowers!)
